The purpose of this study is to investigate the long term outcome of patients who receive hypothermia treatment for spinal cord injury. At this institution, intravascular hypothermia has been used for certain patients with spinal cord injury for the past two years. This study will collect data from vital signs and examinations while the patient is in the hospital and also when they follow up as an outpatient after they are discharged or go to a rehabilitation center. This data will then be analyzed and compared only to historically published data from previous studies. The aim of this investigation is to determine if intravascular hypothermia results in a beneficial outcome for patients with spinal cord injury.

Primary Outcome Measures:
  • International Standards of Neurological Classification for Spinal Cord Injury [ Time Frame: Change from Baseline at 12 months ]

Estimated Enrollment: 100
Study Start Date: January 2007
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Detailed Description:
It is standard practice at this institution for patients with complete acute spinal cord injury to receive hypothermia. Incomplete injuries may also be treated with hypothermia. This will be a prospective analysis of the data collected at our institution from patients with acute spinal cord injury receiving the hypothermia protocol. The care of these patients will not be affected by this research. Data for normothermia (37 degrees Celsius) will be obtained from historical studies analyzing similar patient groups. Patients arriving to this emergency department have a baseline neurological examination in a timely fashion prior to the induction of hypothermia by a neurosurgical attending or resident. All patients have Magnetic Resonance Imaging (MRI) of the injured spinal cord on admission. Patients that are intubated and medically sedated prior to the initial exam by the neurosurgical team are excluded because the exam at that time may be inaccurate. Patients receiving hypothermia are transferred to the Neurosurgical ICU, intubated and sedated using muscle relaxants. Additional forms of sedation including benzodiazepines or dexmedetomidine are routinely used as an adjunct to curtail a shivering response. For all patients receiving hypothermia, an Alsius CoolGard® Icy Catheter is placed into the IVC via the femoral vein and the temperature cooled to target (33 degrees) at the maximum rate (0.5 degrees/hr). Mean arterial pressure (MAP) is kept >90 mm Hg at all times with fluid boluses (Normal Saline or Albumin 5%) or blood transfusions to keep the hematocrit at 30. Hypothermia at 33 degrees is maintained for 48 hours. Blood cultures are performed daily (from both a peripheral site and from the catheter itself) and an Orogastric tube (OGT) or Nasogastric tube (NGT) is placed in each patient. Nutrition is provided as per our current nutritional supplementation protocol. Intravenous fluids consist of Normal Saline at all times unless the serum Na rises above 160. Serum electrolytes, coagulation studies and complete blood count are performed daily. After 48 hours of hypothermia, the patient is rewarmed to 37 degrees at a controlled rate of 0.1 degree/hr. After reaching 37 degrees, the intravenous catheter is maintained for no more than 6 days total to keep the systemic temperature at 37 degrees. Surface cooling techniques are occasionally utilized for the purpose of maintaining normothermia after 6 days. The patients are discharged to rehabilitation after they are stabilized. All patients will be reevaluated at 6 weeks, 6, and 12 months using the ASIA sensory and motor scales with Functional Independence Measures (FIM). A follow-up MRI scan will be done at one year.
